The higher base stats amplify the 10% nature multiplier.
Impish raises Defense by 10% and lowers Sp. Attack by 10%. Physical walls that rely on physical or status moves. 30 Pokemon competitively run this nature.

How to Get
SynchronizeLead with a Impish Pokemon that has the Synchronize ability. Wild Pokemon will match its nature. (Gen 3+)

Nature MintUse an Impish Mint to change stat effects to Impish. The original nature name stays but stats change. (Gen 8+)
Other +Defense Natures
What does the Impish nature do in Pokemon?
It's a +10% Defense, -10% Sp. Attack nature. The 10% multiplier applies after base stats and EVs, so the actual point difference grows as stats get higher. Pokemon with Impish nature prefer Sour flavor and dislike Dry.
What are the best Impish nature Pokemon?
Rhydon, Sandslash, Snorlax, and Tentacruel are among the strongest Impish picks. What they share is a reliance on Defense and little need for Sp. Attack. Check the tier list for current rankings.
Is Impish a good nature for competitive Pokemon?
Yes. It fills a solid niche for defensive builds. You'll see Impish on dedicated Defense-focused builds across most tiers and formats.
How do I get an Impish nature Pokemon?
Three options: (1) Synchronize lead forces wild Pokemon to match your lead's nature. (2) Everstone breeding passes the nature 100% of the time since Gen 5. (3) an Impish Mint changes the stat effects after the fact. Mints don't change the nature name, just the stat modifiers.
Should I use Impish or Bold?
It depends on what your team needs. Impish is the physical defense utility option. Bold is the special defense utility option. Most of the time, your Pokemon's moveset and role make the decision obvious.
